Block of the month exchange

I have been in a block of the month exchange at the Leduc Quilt Guild this past year. I was a little bit behind and did three in Dec to get caught up. Here are the three. The block name is sister's choice. I have three blocks left and then the exchange will be done. I have not seen my blocks yet.
The exchange rules were to do one of your own blocks (12 1/2" square) and then add some of the fabric you want used into your box. Most of us used a 12 " square pizza box. We could do any pattern we wanted to do. One of the boxes, the quilter has asked us to do basket blocks. Some of us have included a book for each quilter to right in. Some people want their blocks signed.
